Been trying to get my bow all set up and tuned for the last few weeks. Got my FP's dialed in and I'm shooting 1-2in at 30yds. Had a few issues with my rest timing and finally got that figured out. I had a few old thunderheads and did some walk back with those. My groupings were a few inches high but dead center. I just got a new string put on with a d loop and that thing just does not want to move. I cannot adjust my QAD up or down. Is it alright to just change my pins for the BH's? My broadheads are hitting the 20yd target on the 30yds pin adjusted for FPs. I put another pin up and sighted that in for BH's at 30yds. I am hitting 2-3in at 30yds with the thunderheads. Are there any issues with doing that? Is it mandatory to have FPs and BHs group together if I am hitting my mark with the BHs?

I am doing that right now. I have a tad too stiff arrows for my compound and cam lean is causing that. So I am hitting 3-4" groups to 40 yards, and I refuse to move my rest over anymore. So I sighted in for BH's. Cam lean is causing me ton of issues and bow has been sent back once.

you should be fine , if you are getting good groups with broadheads , your arrows are flying pretty straight
